| 中文摘要: |
| 基于国内外研究成果,综述了关于轮胎噪声产生机理的定性及部分定量结论,指出轮胎恒速行驶时主要存在3类噪声机理:气流声、机械声和滤波放大机理。举例分析了几种典型花纹的噪声产生机理。同时,简述了轮胎噪声研究建模与预测的发展动向。 |
| 英文摘要: |
| The qualitive and partly quantitive conclusions of tire noise-generating mechanisms are
drawn f rom the previous studies.It is pointed out that there are 3 types of tire noise-generating mechanisms at constant speed ,i. e. airflow noise ,mechanical noise and filter amplification mechanisms. The noise-generating mechanisms of some typical tread patterns are analysed for example. The developing trend of the model establishment and prediction for tire noise are briefly discussed. |
